I purchased it less than 3 months ago and that is how long it worked for me. One day it stopped working for no clear reason. As I was investigating the problem, I discovered that some sort of tiny plastic pivot joint broke, which helps control some a stabilizer bar to hold pencils in place during sharpening. It didn't seem like an essential part of the functionality of the motor or sharpener wheel, but it won't work without it because I think it activates a pressure lever, or electrical ground, for the motor to engage somehow. Anyway, for the money, this device should be sturdier in these components that inherent pressure and stress through simple wear. 3 months hardly worth the effort to buy this machine. I was shocked by all the positive reviews pertaining to this item, or more accurately, how I managed to get one that broke at a weak point in its design.
